I've tried different settings in my kernel config, but can't seem to find the right one. And strange thing is, I used my old kernel config (previous install of gentoo) and then DMA was working and now it isn't!

Any help on this please, I really need DMA to be enabled, it makes a huge difference. Also would like to know how to enable it on my cd-writer (scsi-emulated device on /dev/sr0 ) -- or how to check this?

This way I don't have to use hdparm, but read the help, some bugs or something.

For cdr when I do cat /proc/ide/hdc/settings the using_dma is on, so I think it's using dma (hdparm doesn't work on scsi-emulation)._________________"Remember there's a big difference between kneeling down and bending over.", Frank Zappa
